ODM V8.5 Install fails on top of WAS 8.5.5

I am using Installation Manager to try and install ODM V8.5, but I get to a screen that says to enter path to WAS instance, but when I enter path I get message saying:

The product is unable to determine
which edition of WebSphere Application
Server is installed at the selected
location. Base or Network Deployment
edition of version 8.5.0.0 or later is
required, depending on the features
selected.

After getting this message (Base or Network Deployment edition of version 8.5.0.0 or later is required), I did explicitly installed WAS ND 8.5.0.0 but at that time I did missed the above point
"3) Ensure "Search service repositories during installation and updates" is NOT checked. "
and WAS version was automatically been upgraded to WAS 8.5.5.X...

After re-installing WAS with this check box removed, it now works fine.
